The bezels can fall off at any time and most owners don't even know it happened until they get home. Some even think they're stolen but the only theft going on is how Cadillac convinced them to drop $30,000 on a car that drops plastic at the local car wash.
The problem seems to only happen to 2003 and early-2004 models. At some point during the manufacturing of the 2004, Cadillac switched designs and started bolting in the panels.
Any Chance of a Recall? ∞
The National Highway Traffic Safety Administration (NHTSA) will only intervene in issues where safety is involved, not pride. And trusting Cadillac to do the right thing here is, well ... just don't.
You Want How Much For a Molded Piece of Plastic? ∞
It's such a common problem that replacement parts are hard to come by.
Once you find an OEM replacement it'll run you about $770. Yes, it's just plastic. No, that's not a typo.
So the ridiculous cost + no chance of a recall means most owners check ebay or aftermarket part sites instead. Some have even called junkyards to try and find a replacement but those sharks smell blood in the water and still charge $500 for a non color-matched version.
